Wallace, a longtime backup and part-time starter for the Seattle Seahawks and the Cleveland Browns during his career, would back up recently acquired Matt Flynn in Oakland. Wallace did not play in the NFL last season.

The Raiders decided on Wallace, 32, after several quarterbacks recently worked out for the team. Among those was Tyler Thigpen, whom the Seahawks considered before settling on Brady Quinn as their backup to Russell Wilson. Seattle also reportedly had interest in Wallace.

The addition of a backup makes quarterback Terrelle Pryorís status uncertain in Oakland. The former Ohio State quarterback has struggled in brief appearances with the Raiders, but itís possible the Raiders would look to Wallace to mentor Pryor.
